LONDON Feb 24 (Reuters) - Gay men at high risk of HIV who took a daily dose of a Gilead AIDS drug as a preventative measure cut their risk of infection by 86 percent, according to results of a British trial released on Tuesday.

Researchers who conducted the trial of so-called pre-exposure prophylaxis (PrEP) said the results offer real hope of reversing the HIV epidemic among men who have sex with men, one of the highest risk groups.
